Final answer:
Ancient Roman poets like Catullus and commentators such as Horace indirectly discussed the idea that love might blind one to a partner's flaws, although no specific text from around 35 BC explicitly states that a person in love sees their loved one as perfect.
Step-by-step explanation:
The text written around 35 BC that talks about a person in love seeing their loved one as perfect can be inferred from the works of poets like Catullus and Horace, as well as from legal and funerary inscriptions of ancient Rome. Catullus, for instance, in Poem 75, describes a consuming love for Lesbia, where his devotion is so great it defies both her success and wrongdoing.
This is not a direct statement about seeing a loved one as perfect, but it does illustrate the blinding effect of love. Similarly, in another context, Horace describes the ineffectiveness of love spells concocted by witches, reflecting on the extreme measures some might take to evoke love and, implicitly, the perceived perfection of their objects of desire.
Other examples such as Sulla's elaborate funeral for his wife and Ovid's works, including The Art of Love, may offer indirect reflections on the notion of seeing a loved one as perfect. Nonetheless, none of the sources listed explicitly mention a text from 35 BC that states a person in love will think their loved one is perfect. Possibly, the tender expressions in funerary inscriptions or the exalted descriptions in love poetry could be interpreted as manifestations of this idea.
